The present application provides a method for extracting an extractable component from a feed liquid using a porous membrane. One embodiment of the method includes temperature-swing solvent extraction of water from saline water using a porous membrane.

A saline feed stream flows into a liquid-liquid extraction system; and a volatile organic solvent flows through a main compressor. The compressed volatile organic solvent then flows through a solvent regenerator, which can be a heat exchanger or a combination of a vaporization device and a condenser, to cool the volatile organic solvent. The cooled volatile organic solvent in liquid phase then flows into the liquid-liquid extraction system, where the saline feed stream contacts the volatile organic solvent to selectively extract water from the saline feed stream into the volatile organic solvent, producing a concentrated brine and an organic-rich mixture of water and the volatile organic solvent. The organic-rich mixture flows from the liquid-liquid extraction system into the solvent regenerator, where the organic-rich mixture is heated to produce an organic-rich vapor and desalinated water; and the organic-rich vapor is recycled as volatile organic solvent back into the liquid-liquid extraction system.

A method for desalinating a liquid, including: contacting, within a hydrate former reactor, a feed gas stream including iso-butane in an amount ranging from above zero mol % to about 3 mol % and liquid seawater or liquid wastewater including a dissolved salt, wherein a temperature and pressure within the hydrate former reactor is controlled so that the feed gas stream and the liquid seawater or liquid wastewater form a hydrate slurry; separating hydrate particles from the hydrate slurry; and decomposing the hydrate particles into its constituents of water and gas or gas mixture containing iso-butane, wherein the water has a concentration of the dissolved salt that is less than that of the liquid seawater or liquid wastewater.

Provided is a method for providing an integrated system for water treatment energized by sustainable hydrogen, including the steps of: generating electrical power from at least two renewable power producing systems, wherein the renewable power producing systems comprise at least a solar photovoltaic cell and a wind turbine; converting the electrical power with a controller in electrical communication with the two renewable power producing systems and a power bus to power an electrolyzer.

A system for distilling water is disclosed. The system comprises a heat source, and a plurality of open-cycle adsorption stages, each stage comprising a plurality of beds and an evaporator and a condenser between a first bed and a second bed, wherein each bed comprises at least two vapor valves, a plurality of hollow tubes, a plurality of channels adapted for transferring water vapor to and from at least one of the condenser or the evaporator, a thermally conductive water vapor adsorbent, and wherein each vapor valve connects a bed to either the condenser or the evaporator.

Desalination systems, apparatus, and related methods for use with saline fluids are disclosed. A disclosed desalination system includes an HDH system including a humidifier and a dehumidifier that, together, are configured to process a first saline fluid to produce freshwater in the dehumidifier. The desalination system also includes an AD system operatively coupled to the HDH system. The AD system includes a first bed, a second bed, an evaporator, and a condenser that, together, are configured to process a second saline fluid to produce freshwater in the condenser. The condenser is configured to transfer heat exhausted by the first or second bed from a vapor, obtained from the second saline fluid, to air circulating through the humidifier and the dehumidifier to drive the HDH system. The evaporator is configured to provide a cooling effect.

Systems and methods of performing temperature swing solvent extraction (TSSE) descaling of produced water and desalination of high-salinity brines, e.g., those having a total dissolved solids (TDS) greater than about 250,000 ppm are capable of producing descaled water products including less than about 5% weight percent TDS. The brine/produced water feedstreams and combined with a solvent having temperature-dependent water solubility at a temperature T.sub.L. Water is extracted from the feedstream into the solvent to form a water-in-solvent extract component and a raffinate component, from which a solid phase can be precipitated as more water is portioned in the solvent and basicity increases. Heating of the water-in-solvent extract component reduces the solubility of the water therein, producing a biphasic mixture of dewatered solvent and descaled water that can be separated. Because these systems and methods do not require a phase change of water, these products are achieved with significantly higher energy efficiencies when compared to evaporation-based thermal methods.

The disclosure provides an electromagnetic ionic liquid, which consists of ammonia water, diluent, EWT electronic water and macromolecular complex. The four components are mixed evenly at normal temperature and pressure in a certain proportion to prepare the electromagnetic ionic liquid. The electromagnetic ionic liquid can be used for extracting struvite from seawater, salt water or brine, which improves quality of the struvite, facilitates its industrial production and improves yield of struvite products. In addition, with the electromagnetic ionic liquid, elements required for crop growth and dozens of types of trace elements can be captured in the precipitate, which has great social and economic value for mass production, popularization and application of the struvite.
